Answer:

Step-by-step explanation:

First we must find the x and y intercepts for y = -2x - 4. The y-intercept is -4, since it is b in y = mx + b, but you can also find it by plugging in zero for x:

$y = -2(0) - 4 = 0 -4=-4$

The x-intercept is found by plugging in zero for y:

$0=-2x-4$

$0+4=-2x-4+4$

$4=-2x$

$\frac{4}{-2}=\frac{-2x}{-2}$

$-2=x$

The graph with an x-intercept of -2 and a y-intercept of -4 is C. Also, less than inequalities have the shading underneath the line, so we definitely know C is the answer.

likoan [24]

Answer:

$54.6

Step-by-step explanation:

Amount borrowed = $560

Interest paid in the 12-month period = 6.5% of 560 =$36.4

The amount of interest Trudy pays in 18 months is worked out as

Monthly interest = $36.4/12

Interest payable in 18 months

= ($36.4/12) x 18

= $54.6
